About the Project Applications are invited for a self-funded, 3 year full-time or 6 year part-time PhD project.
The PhD will be based in the School of Computing, Mathematics and Physics and will be supervised by Dr Melvin Vopson and Dr Sergi Simon. This PhD project focuses on advancing Entropic based methods including Barcoding technologies into the digital securities domain. The work on this project will: Expand fundamental research and information theoretic approaches into digital securities applications. Develop functional prototyping software using this technology. Test the technology on real data. Project description: Optically readable barcodes and QR codes are an essential tool in our modern society. These barcodes are randomly generated and associated with an item by simple allocation. If a given barcode is re-allocated to another item, the recorded details within the barcode will no longer represent the characteristics of the new item. When barcoding is applied to sensitive items, such as genetic sequences or financial assets, this becomes a security and privacy problem. A solution is the Entropic Barcoding technology developed by the Information Physics Institute and the University of Portsmouth [1]. This method allows for the creation of Entropic barcodes that are permanently linked to the item they represent. The Entropic barcodes are therefore not transferable. Any changes to the underlying sequence will generally produce changes in the corresponding Entropic barcode, making the representation sensitive to variation. This has recently been applied to blockchains to create an improved blockchain technology called Entropic Blockchain [2]. The proposed technology uses the concept of entropy of data in the framework of Shannon’s information theory to transform any data set (including digital) by simultaneously compressing its digital footprint size, irreversibly encrypting and labeling the data, while also facilitating a unique methodology for data integrity checking, data validation, fraud detection and fast identification via laser barcode scanning. The technology could be used to generate Entropic Barcodes of any kind of dataset, including genomic sequences and digital data files. In this PhD project, the main objective is to expand the fundamental research into digital securities application domain, and to develop prototyping software applications based on the proposed technology. General admissions criteria You'll need a good first degree from an internationally recognised university (minimum upper second class or equivalent, depending on your chosen course) or a master’s degree in an appropriate subject. In exceptional cases, we may consider equivalent professional experience and/or qualifications. English language proficiency at a minimum of IELTS band 6.5 with no component score below 6.0. International students will require a study visa from UKVI to pursue the degree in the UK. If the research is in a sensitive or technological subject, the student may also need to secure an Academic Technology Approval Scheme (ATAS) certificate from the UK Foreign Office. Specific candidate requirements Recommended background knowledge and modules: Statistics, Information Theory, Theoretical Physics, Programming / coding intensive. Additional skills to be acquired during the project: Advanced theoretical understanding of Information Theory and its applications to digital technologies.
